Total resistance=R1+ R2= 6Ω
Voltage=12v
Current =

Current= 2A
In a series circuit, equal current passes through every resistance.
Answer is option A
Answer:
This is because the force of gravity is much less on the moon than on the earth, therefore the person wont be pulled down much and will jump higher
Density =mass/Volume
0.8=mass/60
Mass=0.8*60
Mass=48g
